Connect and brace both ladder frames with two double guardrails. Clip the access deck onto the th rung from the bottom. The snap-on claws of all parts are to be locked onto the ladder frames from above. three-part side guard must be attached when this is required by the regulations applying for the job to be performed. In order to remove the different parts, depress the locking clips of the snap-on claws. The red claws of the deck enable a single person to assemble or dismantle them easily; open them at one end and rest the base of the clips on the rung. Now open the opposite clips and remove the deck.

STOP Õ 330 When the brake is locked, the lever labelled STOP is in the down position. For movement, the castors are unlocked by pushing the other lever down. Wall support under load a side view Top view 8 8 For work performed on a load-bearing wall, ballasting can be reduced in accordance with the ballasting table (see page ). In this case, wall supports must be installed on both sides of the tower. Use a Uni-distance-tube and fix it to the ladder frame, a with the couplers. The mobile beams are to be mounted so that the extension arms project from the side opposite to the wall. The wall supports must be attached at the height of the top working platform or at most m below that. Dismantling During assembly and dismantling, system decks or scaffold planks according to DIN 0-3 (minimum measurement: 8 x. x 0 cm long) must be built in as auxiliary decks at maximum height intervals of.0 m. These auxiliary decks, providing a safe footing for assembly and dismantling, are removed after the erection. Each platform must be completely boarded. To remove the different parts open the snap-on claws by depressing the locking clips.

Couplers with hand wheels permit simple, quick and secure fixing of the respective ballast required at the correct places. Only these ballast weights are to be used, liquid or granular ballast materials must not be used. The ballast weights must be distributed evenly to all ballasting fixing points. The remainder, not divisible by, is distributed to the fixing points.

6 General Instructions on ssembly and Usage The rolling tower may be used for the scaffolding group and as additionally specified in the German operating safety regulations (BetrSichV). The user of mobile working platforms must comply with the following instructions:. The user must check the suitability of the selected rolling tower for the work to be performed (Section of BetrSichV).. The max. platform height is, in accordance with DIN EN 00:00-03 inside buildings.0 m outside buildings 8.0 m The material and ballasting requirements on page must be complied with; risk of accidents in the event of non-compliance. For greater heights, additional measures are necessary, obtainable from the manufacturer. Stability of the rolling tower must be assured. 3. The assembly, modification or dismantling of the rolling tower in accordance with the present instructions for assembly and use may only be performed under the supervision of a qualified person and by professionally suitable personnel after special instruction. Only the scaffolding types shown in these instructions for assembly and use may be used. The unit must, after assembly and before being put into service, be inspected by persons qualified to do so (Section 0 of BetrSichV). The inspection must be documented (Section of BetrSichV). During assembly, modification or dismantling, the rolling tower must be provided with a prohibition sign indicating No access allowed and be adequately safeguarded by means of barriers preventing access to the danger zone (BetrSichV nnex, para...).. Before starting assembly, examine all components in order to make sure they are in perfect condition. Only undamaged original components for Layher Mobile tower systems may be used. Tower parts such as snapon claws and spigot must be cleaned of dirt after use. Tower parts must be protected against slipping and impacts during truck transportation. It must be ensured that the tower parts are stored where they are free from weather effects. Tower parts must be handled in such a way that they are not damaged. For the fixing of ballast weights and wall supports see the tables on page of these ssembly and Use Instructions.. During assembly and dismantling, system decks or scaffold planks according to DIN 0-3 (minimum measurement: 8 x. x 0 cm long) must be built in as auxiliary decks at maximum height intervals of.0 m. Observe the equirements for maximum support distances of scaffold boards according to their thickness. These auxiliary decks, providing a safe footing for assembly and dismantling, are removed after the erection. Each platform must be completely boarded. Edition:..0 Due to structural reasons intermediate platforms with access decks must be built in at maximum intervals of.00 m. For safety reasons, it is advisable for two persons to erect the towers above a height of.0 m. To assemble the upper tower sections, the individual parts must be hoisted using transportation ropes. Small quantities of tools and materials can be carried up in person, otherwise also hoisted by transportation ropes to the working level.. Secure the ladder frame joints with spring clips against unintended lift-off. 7. During assembly push guardrails and diagonal braces outwards as far as possible on the ladder rungs. 8. t intermediate decks used for climbing only, two guardrails are required. For small towers where the height of the deck exceeds.0 m, equipment must be provided that permits the attachement of side guards in accordance with DIN EN 00: ccess to the working platform is only permitted on the inside (exception Tower Type 30) using the ladder rungs provided. 0. It is not permitted to work on two or more decks at the same time. In the event of discrepancies consult the manufacturer.. Persons working on mobile towers should not lean or press against the guardrails, nor jump onto platforms.. It is not permitted to affix lifting or hoisting devices to mobile towers. 3. Move the tower manually and only on firm, level ground which is free from obstacles and sufficiently load bearing. Move the tower only longitudinally or diagonally. void any impact. fter extending the base one-sided with wall supports in use, move parallel to the wall only. Do not exceed normal walking speed during movement.. No persons or loose objects must remain on the tower when moving it.. fter moving the tower, lock the castors by pressing the brake lever.. Do not expose the tower to corrosive liquids or gases. 7. Mobile working platforms must not be bridged between each other, or a building without special verification. The same applies to special erections, e.g. suspende use etc. 8. t a wind force above (Beaufort-Scale) and after finishing the working shift, move the tower when operating outdoors or in open buildings to a wind protected area or secure ot by other approviate measures against toppling over. (Wind speeds above on the Beaufort scale can be recognised by noticeable difficulty when walking.) If possible, rolling towers used on the outside of buildings must be securely attached to the building or to another structure. It is recommended that rolling towers be anchored when they are left unattended.. In order to achieve different working heights decks may be fixed one rung higher or lower. Take care to comply with the prescribed guardrails at heights of m or more. Diagonal braces, too, must be placed a the corresponding lower or higher level. Contact the manufacturer in order to find out whether an additional static calculation will be necessary. void horizontal and vertical loads that can cause the mobile work platform to topple over, such as: - horizontal loads, for example when working on adjacent structures, - additional wind loads (due to tunnel effect from through-type buildings, unclad buildings and corners). 0. Keep the access hatches shut, except when climbing the tower.. The mobile beam may double as a rung for climbing up and down.. ll couplers must be fastened with 0 Nm. 3. Set the rolling tower verhedly by placing suitable materials underneath it. The inclination must not exceed %.. rolling tower is not intended for use as a stairway tower providing access to other structures.. It is prohibited to jump on the decks.. check must be made that all parts, auxiliary tools and safety equipment (ropes etc.) for erecting the rolling towers are available on the site. 7. If stipulated, mobile beams or tower supports or outriggers and ballast must be installed. 8. It is prohibited to increase the height of the decking by using ladders, boxes or other objects.. It is not permitted to construct bridges between the rolling tower and a building. 30. Rolling towers are not designed to be lifted or suspended. ll dimensions and weights are guideline values.
